Carl had been industriously working on this telephoto device during the war. His idea was to observe the movement of the armies, believing that with it he could end the war and prevent all future wars. No military movement would be secret, no advance unobserved, with his machine. The idea was first born in his mind after a talk with a great detective who was looking for evidence against some suspected criminals. Carl had come to the detective’s aid with a device whereby he could see what was going on in a closed room. He placed wires along the picture molding of the room, during the suspected one’s absence, and the four ends of the wire he provided with “eyes,” his secret invention. These wires led from the room to a place at some distance away, where the apparatus reflected the entire room upon a large mirror. This device he had improved upon until at last, instead of wires and the “eyes” he had been able to accomplish the same result by means of wireless. The war over, he continued his experiments on the device, intending to use it in connection with his lectures on city planning. In his delirium, he was addressing a large audience and demonstrating his device. He pointed the indicator to Paris, saying, “Here we have a city, where Baron Hausmann, under the great Napoleon, remodeled the entire city, broke through new thoroughfares, made plazas and squares, at an expense of some two hundred and thirty million dollars. The scene before you is that of the Place du Chatelet, with the monument at the end of the bridge, or rather beyond the bridge, acting as a focal point. Note the good treatment of the traffic waterway, the well planned boulevards, the uniform height of the buildings as well as the ornamental shade trees on both sides of all streets. Surely, here are examples for our American cities.” Turning the indicator upon Duesseldorf, one of the foremost cities, where the art of city planning has been practised for generations, Carl said, “Here is the river promenade on the Rhine in Duesseldorf. Where can we find in our own country a similar scene of such civic improvement? At the lower level you see the electric unloading machinery and the busy vehicles hauling away the freight of the river boats. On the upper level in the wide promenade, flanked on one side with shade trees and on the other with the great balustrade, giving an open view of the river and the monumental bridge in the distance. Observe, also, the highly ornamental electroliers. Duesseldorf is no larger than Jersey City, but who ever goes to Jersey City for the sake of seeing anything beautiful. Where could we, in our own country, find such a scene, as this, of business and pleasure combined. Yet all this could be duplicated in America if the principle were but understood. As will be seen, city planning develops artistic taste, civic pride and patriotism. It also makes for better citizenship, adds to our comfort and our happiness and it stimulates industrial prosperity.
